Abstract
Description
Die Erfindung betrifft ein Befestigungselement zum Verbinden einer Montageschiene mit einer Wand eines Schaltschrankes.The invention relates to a fastening element for connecting a mounting rail to a wall of a control cabinet.
Die meist als Voll- oder Teil-Hohlprofilabschnitte ausgebildeten Montageschienen werden vielfach direkt mit der Wand des Schaltschrankes verschraubt. Dies bereitet dann keine Schwierigkeiten, wenn die Montageschiene parallel zu der Wand ausgerichtet ist und direkt oder über Abstandselemente mit der Wand verschraubt wird. Es müssen jedoch immer mehr Montageschienen auch mit den Stirnseiten auf die Wände stoßend befestigt werden.The mounting rails, which are usually designed as full or partial hollow profile sections, are often screwed directly to the wall of the control cabinet. This is not a problem if the mounting rail is aligned parallel to the wall and is screwed to the wall directly or via spacers. However, more and more mounting rails also have to be fastened with the end faces hitting the walls.
Aus der DE-A-3614034 ist ein Verbindungselement für einen gestellrahmen beschrieben.DE-A-3614034 describes a connecting element for a frame.
Es ist Aufgabe der Erfindung, ein Befestigungselement zu schaffen, mit dem Montageschienen mit den Stirnseiten auf die Wand des Schaltschrankes stoßend schnell und einfach befestigt werden können.It is an object of the invention to provide a fastening element with which mounting rails can be fastened quickly and easily by pushing the end faces onto the wall of the control cabinet.
Diese Aufgabe wird nach der Erfindung dadurch gelöst, daß an eine Stirnseite eines im Querschnitt an den von der Montageschiene umschlossenen Hohlraum angepaßten und in die Montageschiene einschiebbaren Halteblocks eine Anschlagplatte angeformt ist, daß die Anschlagplatte die Stirnseite der Montageschiene überdeckt und mit deren Außenkontur bündig abschließt, und daß zumindest die Stirnseite des Halteblockes mit der Anschlagplatte mit einer Befestigungsbohrung und einem die Befestigungsbohrung umgebenden Dichtungssteg versehen ist.This object is achieved according to the invention in that a stop plate is formed on an end face of a holding block which is cross-sectionally matched to the cavity enclosed by the mounting rail and can be inserted into the mounting rail, that the stop plate covers the end face of the mounting rail and is flush with its outer contour, and that at least the end face of the holding block with the stop plate is provided with a fastening bore and a sealing web surrounding the fastening bore.
Das Befestigungselement braucht nur in den Hohlraum der Montageschiene eingeschoben zu werden, wobei der Halteblock die Montageschiene spielfrei festhält. Die Anschlagplatte begrenzt die Einsteckbewegung des Befestigungselementes und mit dem Dichtungssteg um die Befestigungsbohrung wird die Bohrung in der Wand des Schaltschrankes ringsum abgedichtet, sobald die Befestigungsschraube die Anschlagplatte mit dem Dichtungssteg gegen die Wand des Schaltschrankes zieht und verspannt.The fastening element only needs to be inserted into the cavity of the mounting rail, the holding block holding the mounting rail in place without play. The stop plate limits the insertion movement of the fastening element and with the sealing web around the fastening hole, the hole in the wall of the control cabinet is sealed all around as soon as the fastening screw pulls and braces the stop plate with the sealing web against the wall of the control cabinet.
Die Befestigungsbohrung im Befestigungselement läßt sich nach einer Ausgestaltung dadurch auf beiden Seiten zum Einschrauben von Befestigungsschrauben ausnützen, wenn vorgesehen ist, daß die Befestigungsbohrung als Durchgangsbohrung ausgebildet ist, die sich in Richtung zur Stirnseite ohne Anschlagplatte des Halteblockes leicht konisch verjüngt. Die konische Verjüngung dient der besseren Entformung, wenn das Befestigungselement als Spritzgußteil hergestellt wird.The mounting hole in the fastener can be exploited according to one embodiment on both sides for screwing mounting screws, if it is provided that the mounting hole is formed as a through hole that tapers slightly conically in the direction of the end face without the stop plate of the holding block. The conical taper serves for better demolding when the fastening element is manufactured as an injection molded part.
Die der Anschlagplatte abgekehrte Stirnseite des Befestigungselementes läßt sich dann zur unverdrehbaren Festlegung von Teilen anderer Art ausnützen, wenn vorgesehen ist, daß die der Anschlagplatte abgekehrte Stirnseite des Halteblockes mit zusätzlichen Befestigungsbohrungen versehen ist, die vorzugsweise als Sacklochbohrungen ausgebildet sind. Die Anschlagplatte mit dem Dichtungssteg sorgt dabei wiederum für die Abdichtung der Bohrung in der Wand des Schaltschrankes.The end face of the fastening element facing away from the stop plate can then be used for the non-rotatable fixing of parts of another type if it is provided that the end face of the holding block facing away from the stop plate is provided with additional fastening bores, which are preferably designed as blind bores. The stop plate with the sealing web in turn ensures the sealing of the hole in the wall of the control cabinet.
Nach einer bevorzugten Ausgestaltung ist vorgesehen, daß bei einer C-förmigen Montageschiene mit gegeneinander gerichteten Endschenkeln der Halteblock auf einer Breitseite eine leistenartige Verdickung trägt, die den Einführungsschlitz zwischen den gegeneinander gerichteten Endschenkeln der Montageschiene ausfüllt. Die Verwendung derartiger Montageschienen hat den Vorteil, daß an beliebiger Stelle der Montageschiene zusätzliche Schiebemuttern eingesetzt werden können, an denen weitere Teile befestigt werden können. Auch an den Befestigungselementen, die die Montageschiene an den Wänden des Schaltschrankes trägt, lassen sich zusätzliche Teile befestigen, wenn vorgesehen ist, daß in die Verdickung mindestens eine Befestigungsbohrung eingebracht ist, die vorzugsweise als Sacklochbohrung ausgebildet ist.According to a preferred embodiment, it is provided that, in the case of a C-shaped mounting rail with opposing end legs, the holding block has a strip-like thickening on one broad side, which supports the Fills the insertion slot between the opposing end legs of the mounting rail. The use of such mounting rails has the advantage that additional sliding nuts can be used at any point on the mounting rail, to which further parts can be attached. Additional parts can also be fastened to the fastening elements which the mounting rail carries on the walls of the control cabinet, if it is provided that at least one fastening hole is made in the thickening, which is preferably designed as a blind hole.
Für die Abdichtung der Bohrung in der Wand des Schaltschrankes, die die Befestigungsschraube aufnimmt, kann nach Ausgestaltungen vorgesehen sein, daß der Dichtungssteg im Abstand von den Seitenkanten der Anschlagplatte umlaufend ausgebildet ist, oder daß der Dichtungssteg im Abstand um die Befestigungsbohrung umlaufend ausgebildet ist, wobei im letzteren Fall der Dichtungssteg leichter zu verformen ist.For the sealing of the hole in the wall of the control cabinet, which receives the fastening screw, it can be provided according to embodiments that the sealing web is circumferentially spaced from the side edges of the stop plate, or that the sealing web is circumferentially spaced around the fastening bore, whereby in the latter case, the sealing web is easier to deform.
Das Befestigungselement wird nach einer bevorzugten Ausgestaltung als Kunststoff-Spritzgußteil ausgebildet und hergestellt.According to a preferred embodiment, the fastening element is designed and manufactured as a plastic injection molded part.
Die Erfindung wird anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. Es zeigt:

- Fig. 2 shows the front end of the mounting rail with the fastener in an exploded view.
Von dem boxartigen Schrankkorpus ist ein Teil der Seitenwand 10 und ein Teil der Rückwand 11 gezeigt. Die offene Seite des Schrankkorpus weist den Schließrand 12 auf, der rechtwinklig nach innen gebogen ist und in den senkrecht nach oben gerichteten Schließsteg 13 mit nach außen gerichtetem Anlageflansch 14 übergeht. Im Bereich der Seitenwand 10 wird ein C-förmiger Profilabschnitt, auch als Halfenschienen-Abschnitt bezeichnet, als Montageschiene 20 befestigt. Dabei sind die einander zugekehrten Endschenkel 23 und 25, die sich an die Seitenschenkel 22 und 24 anschließen, gegeneinander gerichtet und stehen im Abstand zueinander, so daß ein durchgehender Einführungsschlitz 29 gebildet ist, der dem Innenraum des Schrankkorpus zugekehrt ist. Die Montageschiene 20 stellt einen Teil-Hohlprofilabschnitt mit einem Hohlraum 26 dar. In die beiden Enden der Montageschiene 20 werden Befestigungselemente 30 von den Stirnseiten her eingesteckt. Die Befestigungselemente 30 tragen Halteblöcke 31, die im Querschnitt an den Querschnitt des Hohlraumes 26 der Montageschiene 20 angepaßt sind. Die der Rückwand 11 und dem Schließrand 12 des Schrankkorpus zugekehrten Stirnseiten der Befestigungselemente 30 sind mit Anschlagplatten 36 abgeschlossen, die die Stirnseiten der Montageschiene 20 überdecken und mit deren Außenkontur bündig abschließen.Part of the
Wie Fig. 2 zeigt, ist in die Stirnseite des Befestigungselementes 30 mit der Anschlagplatte 36 die Befestigungsbohrung 34 eingebracht, die als Sacklochbohrung oder als durchgehende Bohrung ausgebildet sein kann. Bei einer durchgehenden Befestigungsbohrung 34 verjüngt sich die Befestigungsbohrung 34 leicht konisch und zwar ausgehend von der Anschlagplatte 36. Um die Befestigungsbohrung 34 verläuft auf der Anschlagplatte 36 der umlaufende Dichtungssteg 35, der im Abstand den Kanten der Anschlagplatte 36 folgt oder nur die Befestigungsbohrung 34 kreisförmig umschließt.As shown in FIG. 2, the
Ist das Befestigungselement 30 in die Stirnseite der Montageschiene 20 eingesetzt, dann begrenzt die Anschlagplatte 36 die Einsteckbewegung. Die Endschenkel 23 und 25, die Seitenschenkel 22 und 24 sowie der Grundschenkel 21 der Montageschiene 20 umschließen den Halteblock 31 des Befestigungselementes 30 spielfrei und die leistenartige Verdickung 32 füllt den Einführungsschlitz 29 der Montageschiene 20 bündig aus. Die Befestigungsschrauben 38 werden durch Bohrungen im Schließrand 12 und in der Rückwand 11 hindurch in die Befestigungsbohrungen 34 der Befestigungselemente 30 eingeschraubt. Dabei werden die Anschlagplatten 36 gegen den Schließrand 12 und die Rückwand 11 gezogen und verspannt, so daß sich die Dichtungsstege 35 der Anschlagplatten 36 verformen und die Bohrungen im Schließrand 12 und der Rückwand 11 zum Innenraum des Schrankkorpus hin eindeutig abdichten.If the
Der Einführungsschlitz 29 erlaubt in bekannter Weise das Einbringen von Schiebemuttern an beliebiger Stelle und deren unverlierbare Festlegung, so daß auch weitere Befestigungsteile, wie z.B. der Befestigungswinkel 40, an der Montageschiene 20 festgeschraubt werden können, wie die Schraube 41 zeigt.The
Die der Anschlagplatte 36 abgekehrte Stirnseite des Befestigungselementes 30 kann weitere Befestigungsbohrungen 37 tragen, so daß bei der Verwendung des Befestigungselementes 30 ohne die Montageschiene 20 weitere Bauteile an dieser Stirnseite des Befestigungselementes 30 unverdrehbar befestigt werden können.The end face of the fastening
